Definitions

  • connection device 2a is also inserted with wedge-shaped rails 10 between a corresponding strip and lower surface (shown separately in this exemplary embodiment). Furthermore, a locking cam 23 is formed on the coil body 2a, which passes through a guide channel 24 when the connection device 2a is inserted and then engages behind a locking pawl 25.
  • the guide channel 24 is laterally delimited by two guide strips 26 and 27.

Abstract

Une bobine d'allumage comprend un corps pourvu d'un enroulement en fil métallique. Un organe de raccordement (2) couplé sur le corps (3) de la bobine comprend des éléments de liaison (13, 14) du début (16) et de la fin (17) de l'enroulement en fil métallique. Les éléments de liaison se composent de ressorts de contact (13, 14) ayant une pince de serrage (15) du début et de la fin de l'enroulement en fil métallique qui traverse l'organe de raccordement et se termine par une fiche, ce qui permet d'établir un contact avec une contre-fiche.

Claims (9)

  1. Bobine d'allumage comportant un corps de bobine présentant un enroulement filaire et auquel est accouplé un dispositif de raccordement équipé d'éléments pour assurer la liaison du début et de la fin de l'enroulement, caractérisée en ce que les éléments de liaison sont constitués par des ressorts de contact (13, 14) portant des pièces de serrage (15) destinées au début (16) et à la fin (17) de fil constituant l'enroulement.
  2. Bobine selon la revendication 1, caractérisée en ce que les éléments de liaison comportent une pièce de serrage (15a) destinée à un fil de masse.
  3. Bobine selon la revendication 1, caractérisée en ce que les ressorts de contact (13, 14) traversent le dispositif de raccordement (2) et se terminent par des broches (22) dans l'ouverture (21) d'un connecteur embrochable.
  4. Bobine selon une des revendications 1 à 3, caractérisée en ce que le corps de bobine (3) reçoit au moulage un ressort d'arrêt (5) servant à accoupler le dispositif de raccordement (2).
  5. Bobine selon la revendication 4, caractérisée en ce que le ressort d'arrêt (5) a la forme d'un T dont la tête transversale vient, en position d'utilisation, se placer sous le dispositif de raccordement (2), en prise derrière un rebord d'arrêt (12) de ce dispositif de raccordement (2).
  6. Bobine selon une des revendications 1 à 3, caractérisée en ce que le corps de bobine (3a) reçoit au moulage une dent d'arrêt (23) servant à accoupler le dispositif de raccordement (2a).
  7. Bobine selon la revendication 6, caractérisée en ce que la dent d'arrêt (23) vient se placer en position d'arrêt, guidée par un canal (24) entre deux barrettes de guidage (26, 27),et ainsi vient en prise derrière un cliquet d'arrêt (25).
  8. Bobine selon au moins une des revendications 1 à 7, caractérisée en ce que le dispositif de raccordement (2) comporte un rail (10) qui assure son guidage entre les barrettes (9) et une portée inférieure (11) du corps de bobine (3).
  9. Bobine selon la revendication 8, caractérisée en ce que le rail (10) et la portée inférieure (11) ont des lames en coin, de sens opposés.
